Shear-thickening and the glass transition
Seminar Room 1, Newton Institute
Some liquids become more viscous when sheared, even to the point of jamming completely. In some cases, this phenomenon can be interpreted as a shear-induced glass transition. A theory that explains shear-thickening in these systems must simultaneously provide an explanation for their glass transition, and, conversely, a theory of the glass transition must naturally incorporate shear-thickening in order to be credible. I will describe a schematic model that reproduces qualitatively the observations, and makes several predictions, some of which have been already tested.
